Check Digit Verification of cas no

The CAS Registry Mumber 126474-03-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,4,7 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126474-03:
(8*1)+(7*2)+(6*6)+(5*4)+(4*7)+(3*4)+(2*0)+(1*3)=121
121 % 10 = 1
So 126474-03-1 is a valid CAS Registry Number.

INTRAMOLECULAR INVERSE ELECTRON DEMAND DIELS-ALDER REACTIONS OF PYRAZINES

Biedrzycki, Marek,Bie, Dick A. de,Plas, Henk C. van der

, p. 6211 - 6220 (2007/10/02)

Thermally induced intramolecular Diels-Alder cyclisations of (alkynyloxyalkyl)pyrazines to dihydropyranopyridines have been studied in the solvent undecane.The introduction of a phenyl group in the α-position of the 3-butynyloxymethyl side chain leads to a 3-4 fold increase of the reaction rate, while the influence of a γ-phenyl group on the rate is negligible.The (3-butynyloxymethyl)pyrazine reacts about 7 times slower than the (3-propynyloxyethyl)pyrazine; the presence of a trimethylsilyl group at the terminus of the alkyne decreases in general the rate of the intramolecular cyclisation.The mechanisms are discussed.
